## Kubernetes GitOps Configuration Example with Argo CD  [![Twitter](https://img.shields.io/twitter/follow/piotr_minkowski.svg?style=social&logo=twitter&label=Follow%20Me)](https://twitter.com/piotr_minkowski)

Here's the current structure of the repo (will be modified soon):

```shell

├── apps

│   └── cert-manager

│       ├── secrets.yaml

│       ├── certificates.yaml

│       └── cluster-issuer.yaml

└── bootstrap

    ├── Chart.yaml

    ├── templates

    │   ├── cert-manager.yaml

    │   ├── postgresql.yaml

    │   ├── projects.yaml

    │   ├── vault.yaml

    │   └── vault-config-operator.yaml

    └── values.yaml

```

For now, it shows how to install and use in the GitOps way:

1. [cert-manager](https://cert-manager.io/) via Helm chart

For more information you can refer to the articles:

1. [Testing GitOps on Virtual Kubernetes Clusters with ArgoCD](https://piotrminkowski.com/2023/06/29/testing-gitops-on-virtual-kubernetes-clusters-with-argocd/)

## Getting Started

You can test the configuration on the virtual Kubernetes cluster using the [vcluster](https://www.vcluster.com/) tool. In order to that create the ArgoCD `ApplicationSet` based on the cluster generator:

```yaml

apiVersion: argoproj.io/v1alpha1

kind: ApplicationSet

metadata:

  name: config

  namespace: argocd

spec:

  generators:

    - clusters: # (1)

        selector:

          matchLabels:

            argocd.argoproj.io/secret-type: cluster

  template:

    metadata:

      name: '{{name}}-config-test'

    spec:

      destination:

        namespace: argocd

        server: https://kubernetes.default.svc

      project: default

      source:

        helm:

          parameters:

            - name: server

              value: '{{server}}'

            - name: project

              value: '{{metadata.labels.loft.sh/vcluster-instance-name}}'

        path: bootstrap

        repoURL: https://github.com/piomin/kubernetes-config-argocd.git

        targetRevision: '{{metadata.labels.loft.sh/vcluster-instance-name}}'

      syncPolicy:

        automated: {}

        syncOptions:

          - CreateNamespace=true

```

If you just want to test on the single cluster managed by ArgoCD you can create the following ArgoCD `Application`:

```yaml

apiVersion: argoproj.io/v1alpha1

kind: Application

metadata:

  name: config

  namespace: argocd

spec:

  destination:

    namespace: argocd

    server: https://kubernetes.default.svc

  project: default

  source:

    path: bootstrap

    repoURL: https://github.com/piomin/kubernetes-config-argocd.git

    targetRevision: HEAD

  syncPolicy:

    automated: {}

    syncOptions:

      - CreateNamespace=true

```
